# The systemd-tmpfiles has the ability to grab information
|
||||
# from the filesystem (instead from the running system).
|
||||
#
|
||||
# tmpfs directories (/tmp, /proc, ...) are skipped since they're not
|
||||
# relevant for the rootfs image.
|
||||
#
|
||||
# However there are a few specifiers that *always* will grab
|
||||
# information from the running system examples are %a, %b, %m, %H
|
||||
# (Architecture, Boot UUID, Machine UUID, Hostname).
|
||||
#
|
||||
# See [1] for historic information.
|
||||
#
|
||||
# This script will (conservatively) skip tmpfiles lines that have
|
||||
# such an specifier to prevent leaking host information.
|
||||
#
|
||||
# shell expansion is critical to be POSIX compliant,
|
||||
# this script wont work with zsh in its default mode for example.
|
||||
#
|
||||
# The script takes several measures to handle more complex stuff
|
||||
# like passing this correctly:
|
||||
# f+ "/var/example" - - - - %B\n%o\n%w\n%W%%\n
