💖 cvsd-buildroot 💖

okay so bestie, this is the cvsd-buildroot(8) page from the System Manager's Manual, and it's literally the glow-up artist for your chroot jail. no cap.

✨ NAME ✨

cvsd-buildroot — create a chrooted directory structure for use in cvsd. 💅

🎀 SYNOPSIS 🎀

cvsd-buildroot DIRECTORY

🦋 DESCRIPTION 🦋

So cvsd-buildroot creates and populates a directory that you can use as a chroot jail for running cvsd in (go peek at cvsd(8) for that part 👀).

fr fr, run this as the root user — creating devices and changing ownership and permissions literally require it, no workaround, periodt.

The script also gives you warnings about files it's not expecting, like a friend who's gently like "bestie… what is this" 🫶

Here's the directory structure cvsd-buildroot builds out, and honestly it ate:

  • /bin — this one gets populated with the cvs binary that's found on your system. main character binary energy.
  • /lib — populated with all the libraries required for running programs in the /bin directory, plus some predefined required libraries that are present on the system. it's giving dependency support 💖
  • /dev — this is where the null and zero devices get created. tiny but iconic.
  • /etc — in here a passwd file is created that's used for matching user id's with usernames. the root and cvsd user are added to this file if they're not there yet. the passwd file is checked for consistency with the system /etc/passwd to prevent mistakes. it's also populated with users referenced in the repository directories. note that no password data from /etc/passwd or any other file is stored in the generated passwd file — all password entries are set to ‘x’. keeping it mysterious, as she should. 🙈
  • /usr — here symbolic links are placed to /bin and /lib for some common library and binary directories found on the system. this is done for systems that have hard-coded paths for libraries. we love an accessibility queen 🌈
  • /libexec and /usr/libexec — symbolic links for these directories are created if they are present on the system. conditional slay.
  • /tmp — this directory is cleaned out on systems that have tmpreaper. fresh start vibes ✨

After all the directories are created and populated, ownership and rights are set to a reasonable value — that's root:root,umask=022. tidy. 💅

🌸 OPTIONS 🌸

  • cvsd-buildroot takes one argument, namely a directory in which the chroot jail will be created. The directory should be specified with an absolute path. that's it, that's the whole menu — one item, but she's everything 🎀

💀 NOTES 💀

Creating a chroot environment is a terribly non-portable thing to do and therefore you may experience problems with missing libraries and system files. it's not you, it's the portability 😭 for more information see the FAQ and the README.

If you have to install libraries or perform actions not covered by cvsd-buildroot please report your findings to <cvsd-users@lists.arthurdejong.org>. the maintainers wanna hear it, fr fr 🫶

Rerunning cvsd-buildroot after you have created your repository is advised since the repositories are checked for references to userid's and lockfile directories. so like, come back and run it again bestie, it's a vibe check on your repo 👑
