💅 syste...linux(8) — SELinux Policy for systemd_bless_boot_generator ✨

okay so bestie, welcome to the man page for the SELinux policy that wraps around systemd_bless_boot_generator — it lives in the syste...linux(8) manual section and it's genuinely so much. grab a boba, we're doing this 🧋💖

---

🌸 NAME 🌸

systemd_bless_boot_generator_selinux — Security Enhanced Linux Policy for the systemd_bless_boot_generator processes. that's the whole vibe. she does exactly what it says on the tin 🎀

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the systemd_bless_boot_generator processes via flexible mandatory access control. yes, flexible AND mandatory at the same time, she contains multitudes 💅

The systemd_bless_boot_generator processes execute with the systemd_bless_boot_generator_t SELinux type. you can check if you've got these processes running by executing the ps command with the -Z qualifier. iconique. for example:

ps -eZ | grep systemd_bless_boot_generator_t

that's it, that's the check 🫶

---

🚪 ENTRYPOINTS 🚪

The systemd_bless_boot_generator_t SELinux type can be entered via the systemd_bless_boot_generator_exec_t file type. like that's the door you walk through, no cap 🚪✨

The default entrypoint paths for the systemd_bless_boot_generator_t domain are the following:

/usr/lib/systemd/system-generators/systemd-bless-boot-generator

one single path, living her best solo life 🌟

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. very main character of her, honestly 👑

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux systemd_bless_boot_generator policy is very flexible, allowing users to setup their systemd_bless_boot_generator processes in as secure a method as possible. lowkey obsessed with how customizable this is 🔥

The following process types are defined for systemd_bless_boot_generator:

systemd_bless_boot_generator_t

Note: semanage permissive -a systemd_bless_boot_generator_t can be used to make the process type systemd_bless_boot_generator_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she's off the leash but she's still journaling about it fr fr 🙈

---

🦋 BOOLEANS 🦋

SELinux policy is customizable based on least access required. systemd_bless_boot_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_bless_boot_generator with the tightest access possible. tightest access possible = the slayest access possible, iykyk 💜

• daemons_dontaudit_scheduling — if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default. ✨

setsebool -P daemons_dontaudit_scheduling 1

• fips_mode — if you want to allow all domains to execute in fips_mode, you must turn this one on. Enabled by default. 🔐

setsebool -P fips_mode 1

both already on by default, so she's pre-blessed, we love a low-effort win 🎀

---

📁 MANAGED FILES 📁

The SELinux process type systemd_bless_boot_generator_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and heads up bestie: the processes' UID still needs to have DAC permissions — SELinux isn't out here overriding that, no ma'am 💅

look at all those paths, she's got range 💀✨

🎀 FILE CONTEXTS 🎀

SELinux requires files to have an extended attribute to define the file type. it's giving "everything needs a little name tag" 🏷️

You can see the context of a file using the -Z option to ls.

Policy governs the access confined processes have to these files. SELinux systemd_bless_boot_generator policy is very flexible, allowing users to setup their systemd_bless_boot_generator processes in as secure a method as possible.

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the systemd_bless_boot_generator. if you wanted to store files with these types in a different path, you need to execute the semanage command to specify alternate labeling, and then use restorecon to put the labels on disk. like so:

semanage fcontext -a -t systemd_bless_boot_generator_exec_t '/srv/systemd_bless_boot_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_bless_boot_generator_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🌸

The following file types are defined for systemd_bless_boot_generator:

• systemd_bless_boot_generator_exec_t — set files with the systemd_bless_boot_generator_exec_t type if you want to transition an executable to the systemd_bless_boot_generator_t domain. 🚪
• systemd_bless_boot_generator_unit_file_t — set files with the systemd_bless_boot_generator_unit_file_t type if you want to treat the files as systemd bless boot generator unit content. 📄

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. temporary vs permanent, choose wisely bestie 💀🙈

---

💻 COMMANDS 💻

• semanage fcontext can also be used to manipulate default file context mappings.
• semanage permissive can also be used to manipulate whether or not a process type is permissive.
• semanage module can also be used to enable/disable/install/remove policy modules.
• semanage boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings. yes queen, a whole GUI 👑
