Subject: [PATCH 056/124] common-ha: fixes for Debian-based systems
1) Debian-based systems don't have /usr/libexec/... and there is
a hard-coded invocation of /usr/libexec/ganesha/ganesha-ha.sh within
ganesha-ha.sh itself.
Fix: save $0 and use it instead for further invocations of self.
2) default shell is /bin/dash (not /bin/bash). Various runner_run()
invocations for ganesha used what amounts to
exec("sh /usr/$libexec/ganesha/ganesha-ha.sh ...);
which executes the script using the default shell, but there are
some bash-specific idioms that don't work if the shell is dash.
Fix: change to exec("/usr/$libexec/ganesha/ganesha-ha.sh ...); so that
the shebang forces the use of /bin/bash
3) Fedora and RHEL7 have merged /bin/ and /usr/bin, /bin is a symlink
to /usr/bin. Debian-based systems are not merged, and systemd systems
have /bin/systemctl. The logic to find .../bin/systemctl is backwards.
If the logic looks for /usr/bin/systemctl it will not find it on
Debian-based systems; if it looks for /bin/systemctl it will find it
on Fedora and RHEL by virtue of the symlink. (RHEL6 and others will
find their respective init regardless.)
Fix: change the logic to look for /bin/systemctl instead.
4) The logic for deciding to run systemctl (or not) is a bit silly.
Fix: simply invoke the found method via the function pointer in the
table.
