system...elinux(8)

💖 NAME 💖

okay so bestie, gather round — this is the manual for systemd_anaconda_generator_selinux(8), aka the Security Enhanced Linux Policy for the systemd_anaconda_generator processes. that's the whole vibe. the SELinux policy page. periodt. 👑

---

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the systemd_anaconda_generator processes via flexible mandatory access control. no cap, that's literally what it does. 🛡️

the systemd_anaconda_generator processes execute with the systemd_anaconda_generator_t SELinux type. wanna check if you got these processes running? run the ps command with the -Z qualifier. slay.

for example:

ps -eZ | grep systemd_anaconda_generator_t

---

🚪 ENTRYPOINTS 🚪

the systemd_anaconda_generator_t SELinux type can be entered via the systemd_anaconda_generator_exec_t file type. that's the doorway, iykyk. 🚪✨

the default entrypoint paths for the systemd_anaconda_generator_t domain are the following:

/usr/lib/systemd/system-generators/anaconda-generator

---

🌈 PROCESS TYPES 🌈

SELinux defines process types (domains) for each process running on the system. every process gets a lil identity fr fr.

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_anaconda_generator policy is very flexible allowing users to setup their systemd_anaconda_generator processes in as secure a method as possible. flexible AND secure?? main character energy honestly.

the following process types are defined for systemd_anaconda_generator:

• systemd_anaconda_generator_t

Note: semanage permissive -a systemd_anaconda_generator_t can be used to make the process type systemd_anaconda_generator_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it stops blocking you but it's still gonna be in your notifications telling on you. 💀

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. systemd_anaconda_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_anaconda_generator with the tightest access possible. tightest access possible = the girlboss approach. 💅

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

setsebool -P daemons_dontaudit_scheduling 1

if you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

---

📁 MANAGED FILES 📁

the SELinux process type systemd_anaconda_generator_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. Note: the processes UID still need to have DAC permissions. (SELinux said yes but DAC said no, that's still a no bestie 🙈)

🗂️ FILE CONTEXTS 🗂️

SELinux requires files to have an extended attribute to define the file type. it's giving ✨metadata✨.

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_anaconda_generator policy is very flexible allowing users to setup their systemd_anaconda_generator processes in as secure a method as possible. (yes bestie, we said this already, it's that serious.)

⭐ STANDARD FILE CONTEXT ⭐

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

semanage fcontext -a -t systemd_anaconda_generator_exec_t '/srv/systemd_anaconda_generator/content(/.*)?'
restorecon -R -v /srv/mysystemd_anaconda_generator_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies stay winning 🧚

the following file types are defined for systemd_anaconda_generator:

systemd_anaconda_generator_exec_t

• set files with the systemd_anaconda_generator_exec_t type, if you want to transition an executable to the systemd_anaconda_generator_t domain.

systemd_anaconda_generator_unit_file_t

• set files with the systemd_anaconda_generator_unit_file_t type, if you want to treat the files as systemd anaconda 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 = cute for a sec, permanent = commit to it 💖

---

🛠️ 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. a GUI!! for the girlies who prefer clicking over typing, we see you 🫶

and that's the whole page bestie, tysm for reading 💖 this one came from systemd_anaconda_generator, dated 26-09-29, and yeah the header up top really does just say system...elinux(8) because even manpages get truncated sometimes 😭 stay safe out there, and remember: restorecon before you wreckon. ✨🦋
