Subject: dracut: don't skip zero-length string outfile argument
X-Git-Tag: 010~23
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dbf381f7fb369bd6336272847da882d8ef0e5a30;p=platform%2Fupstream%2Fdracut.git

dracut: don't skip zero-length string outfile argument

When '' was passed as outfile, dracut generated name with following
pattern:

  /boot/initramfs-$kernel

With commit 486a1b9324d6fc7bc534d8147d64b8b259692c46 dracut skips ''
argument.
