crond won't start. Problem with temp directory /run/cron?
A week ago I updated my wife's computer, and after a few days noticed that crond wasn't running. Running crond -d wasn't much useful, so I ran strace crond -d`. This error appears:
openat(AT_FDCWD, "/dev/null", O_RDWR) = 0
dup2(0, 0) = 0
dup2(0, 1) = 1
brk(NULL) = 0x1dab000
brk(0x1dcc000) = 0x1dcc000
getpid() = 1405
mkdir("/run/cron/cron.I23Z7s", 0700) = -1 ENOENT (No such file or directory)
dup(2) = 3
fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
fstat(3, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
write(3, "mkdtemp: No such file or directo"..., 35mkdtemp: No such file or directory
BTW, OS is Slackware64-current.
Extra info:
I just detected that I can start rc.crond manually (as root), but it doesn't start when rebooting... and it works correctly, executing all the cron tasks.

does the directory /run/cron exist and have permissions that allow cron to create temp files?
– Jeff A
yesterday
It did have permissions, and the directory seems to be generated on boot. But the problem was different, see answer below.

After some discussion on the ##slackware IRC channel about how this problem could occur, I noticed that there was a difference in the /etc/rc.d/rc.M file in my computer and the one at one of the participants.
Older versions of Slackware seem to manage the crond startup directly, while newer versions do this task indirectly by calling rc.crond start. rc.crond does some extra work. Normally this should have been updated automatically, but, for some reason, it wasn't (the rc.M.new hadn't replaced the original file).
