s6

  • contents for bundles has been deprecated, use contents.d instead
  • dependencies has been deprecated, use dependencies.d instead
  • s6-rc-db does not do topological sorting on compiled databases when listing dependencies (open a feature request)
  • /dev/fd exists on other unices and is provided under Linux for compatibility. /proc/*/fd is specific to Linux.
  • sysctl() the syscall is officially deprecated, but the binary sysctl is what is recommended nowadays and uses /proc/sys
  • Do not mount /dev/shm as we’re symlinking it to /run/shm which is also tmpfs
  • /tmp is a symlink to /run/tmp which gets created on every boot (the symlink however gets created only once at the start of bootstrapping/installing the system /tmp)
  • .ICE-unix and .X11-unix in /tmp belong to Xorg and have been removed
  • fsck depends on sys to check for some features (and we should leave it to the initramfs?)
  • Consider having a virtual or a dev to bundle some services (like core, devpts, fd and shm)
  • We want to be initramfs agnostic, so use mountpoint to check for proc and sys (no need for devtmpfs becuase the kernel has options for automount and we can control that)
  • We need cgroup2 to be used as older versions rely on tmpfs on /sys/fs/cgroup
  • 66, anopa and slew are based on s6/s6-rc
  • efivars gets automatically mounted over at /sys/efi/firmware/efivars when using booster; requires a separate service for iso
  • Do not remove sh -e from shebang in rc scripts or use execlineb -P or remove exec
  • devpts does not get mounted automatically at boot or with mount -a and requires a separate mount devpts
  • shm requires chmod 1777 /dev/shm to restore correct permissions
  • Do not provide /usr/bin/modules-load and /etc/sysctl.d; systemd stuff
