Anacron does not correctly check configuration parameters for validity and can segfault on certain data types. The return code from the match_rx calls in readtab.c are not being checked correctly.

build-sys: make ./configure to seach vi path
Using "/usr/ucb/vi" as defaut fallback EDITOR is not going to work on
most of distributions where this package is installed. That said it
might work somewhere, so searching the vi editor at configure time is the
sensible thing to do, if user does not want to define the default.

includes: make inclusions clean
This change makes files to include what they need, instead of having
generic inclusion headers which will include everything to everywhere.
Also the local headers havee ifndef & define protection, which makes them
to be save to include in any file, without one having to think in which
order the inclusions happen at compile time.

cron to not overwrite this path for itself or for the child cron

Previously, crond exited in the signal handler for SIGINT and SIGTERM.
Thus, the Inotify close code in main() was never reached. This commit
introduces a got_sigintterm variable that is set when SIGINT or SIGTERM
are received and leads to a clean exit of the main loop.
* src/cron.c: Rename quit() to sigintterm_handler(). Add got_sigintterm
variable and set it on SIGINT and SIGTERM. Shorten sleep and exit main
loop on got_sigintterm.

9th bit is overwritten.
Hour bit fields have 24 bits (0..23, 3 bytes). bit_nclear() however in this case is called to clear bits 0..24! Thus, it overwrites the first bit of the following struct member (dom). This is not problematic for normal use as dom is set after hour as are all other fields.
The last field, dow, uses 8 bits so 9 are cleared. This could be the MIN_STAR bit of flags, but as flags is an int, there is probably a padding byte in between; at least I couldn't trigger it to be unset. So this could probably only cause problems on 8-bit systems.
This unit file is used in Fedora. The systemd-user-sessions.service guarantees
everything, what is needed for log in of users, is already running
(ypbind, sssd, ldap, ...).
Cron writes job output to syslog incorrectly. When cron is invoked in a way to print job output to syslog, it does print only the first character of the output. Author: Vitezslav Cizek
