/proc available in cpanel, ensim, other shared /virtual hostings?
I'm writing a script that polls data from various sources in /proc (for Linux) and, amongst others, sysctl in FreeBSD, and would like to know how frequently these resources are read-accessible for apache in various virtual hosting environments. Is the script likely to work on hosts using cpanel, ensim, plesk, etc. ? Under what kind of accounts will it be likely to work?
