Fix splitting spaces in paths from statetab files #471

Closed deajan closed 5 months ago

deajan commented 5 months ago

Noticed that paths with spaces in /etc/statetab and /etc/statetab.d/* weren't interpreted. Since a for loop was used, bash just splitted paths at default IFS chars.

Since we could have paths with spaces like /opt/my service in statetab, we need to read the statetab files line per line, with IFS being '\n', which can be accomplished by using a while loop. This is already done for rwtab.

PR initially fixed defect SC2013. Got complaints from shellcheck about new SC2162 defect.

Initially wanted to code comply with current implementation of readonly-root script where rwtab's while loop didn't mangle backspaces (no SC2162 fix).

So updated this PR to fix SC2162 including the one from rwtab's while loop.

Has been tested on a couple of RHEL 9 setups with both rwtab and statetab entries.

[EDIT] I understand that readonly-root is deprecated. But it still has full RHEL 9 support until 2031, so I do think it's a good idea to have that little bug fix included :) [/EDIT]
