Try it and see.
It is why `suidregister` is not working when called from postinst
scripts. The grep in `suidregister`[1] fails, returning code 1 when
it cannot find the regex in the "/etc/suid.conf" file, and since '-o
errexit' (aka 'set -e') is on, the `suidregister` script exits.
I think that this is counterintuitive, and that '-o errexit' should
have file-local (and even function-local) scope. It seems like a bug
in BASH to me.
`suidregister` works fine from a commandline, since '-o errexit' is
not set then.[2] After it's been run once, and the entry that gets
`grep`ped for has been written to "/etc/suid.conf", it works fine from
inside a postinst too, since then the `grep` doesn't return code 1, as
it has something to find this time.
Footnotes:
[1] In the line that reads "X=..."
[2] Or the shell will exit on any error return; I tried it.
