Package Management Policy

Package management is dependent on limited web servers, making parallelization harder. glaucus uses the filesystem tree as its database to store package metadata and recipes.

Cerata

  • Avoid versions in nom
  • Patches are typically applied in prepare
  • Patches should use -p0
  • Packages that use autoreconf, need runstatedir (copied from the system)
  • Group commands that deal with multiple arguments into one (if that applies, e.g. cp, rm, mkdir (if same permissions)…)
  • Group commands that are repeated 3 or more times into for loops
  • Packages should not install to the following directories: /boot, /dev, /mnt, /run, /sys, /tmp
  • Do not store commands inside variables: https://www.unix.com/unix-for-dummies-questions-and-answers/247059-run-command-stored-variable.html

Repository Layout

  • /var/cache/rad/pkg (binary packages, contains sac (DESTDIR) + tarball + sum)
  • /var/cache/rad/src (source tarballs, read-only, equals SRCD)
  • /var/lib/rad/clusters/cerata (official cluster, equals CERD)
  • /var/lib/rad/clusters/custom (custom cluster)
  • /var/lib/rad/pkg (track installed packages using another form of metadata, with checksums and files)
  • /var/log/rad (log files, equals LOGD)
  • /var/tmp/rad (temporary build files)

Local

Remove additional files:

  • .a (static libraries)
  • .alias
  • .bs (perl files)
  • .dbg
  • .la (libtool archives)
  • .packlist (perl files) (alpine removes them)
  • .pod (perl files) (void removes them)
  • .py (python files)
  • .pyc (python files) (ewe removes them)
  • .pyo (python files) (ewe removes them)
  • alias
  • charset
  • completions
  • extralibs.ld (perl files)
  • locale
  • systemd
  • test (ewe removes them)

Out of Tree Builds

Toolchain:

  • binutils
  • gcc

Cross:

  • binutils
  • dash (no patches applied so no need to copy src)
  • e2fsprogs
  • gcc
  • iputils
  • less
  • lksh
  • mksh
  • musl-utils (has no package source though, as its files are in CERD)
  • which
