The Linux /sys fs is truly bizarre. On a RaspberryPi running Linux 4.4.21+:
$ find /sys | wc # total entries
11448
$ find /sys -type l | wc # count of symlinks
1077
$ find /sys -type f | wc # count of "regular" files
8931
I am not sure exposing most everything via a namespace in this
manner is such a good idea (or at least in "good taste" :-)
Interfaces should be lean.
Similarly the /proc fs is quite strange. Why does it have any
non process subdirectory?
$ echo /proc/[0-9]* | wc -w # count of processes
142
$ echo /proc/[^0-9]* | wc -w # count of non-process directories
58
Compare:
Linux (raspberryPi + X windows):
$ echo /proc/[0-9]* |wc -w # how many processes
142
$ find /proc/[0-9]* | wc -l # how many proc related files+dirs
66153
FreeBSD (10.3 amd64+zfs+4 lightweight jails):
$ echo /proc/[0-9]* | wc -w # how many processes
123
$ find /proc/[0-9]* | wc -l # how many proc related files+dirs
1075
Plan9 (mostly quiescent):
$ echo /proc/[0-9]* | wc -w
64
$ du -a /proc/[0-9]* | wc -l
1235
Anyone feeling sad about /proc in FreeBSD should consider
the alternative!
