I'm working under some constraints of a runtime that do not allow me to exec processes but that is exactly what I need to do. The runtime does have normal user write access to the filesystem. Can anyone think of some way with only normal user write access to start a process? Is there some /dev /sys or /proc file I can write to that will exec a process? If not I might have to resort to having it exec by adding something to the user's crontab, but that will assume that the user has the correct group / permissions. So it would be nice if there was some other way. Thanks!
