macros.initrd

# Packages installing files and binaries that end up in the initrd should
# call these macros in their post(trans) scriptlets to have the initrd
# regenerated
# See also fate#313506

# mkdir is part of the coreutils package. When the post scriptlet of some
# package using regenerate_initrd_post is run, the mkdir command may be
# unavailable. This is non-fatal, because in all cases that matter for initrd
# generation, coreutils will be part of the same transaction and will trigger
# an initrd rebuild later. See boo#1217775.
# 
# Anyway, packages can use the regenerate_initrd_requires macro below to make
# sure mkdir is available in their post scriptlet. Use if this macro is not
# mandatory.
