mkfifo: cannot create fifo '/compile/firefox/logpipe.uagECToo': Operation not permitted
I did open acces to user root to this directory after this happend.
It did not help.
It is a sshfs by sshd directory/filesystem on ext4.
My pc compiles and uses anothers pc free disk space.
(Another pc can not compile because it has unauthorised(forbidden) memory access error(SIGVI of something similar) when compiiling firefox. I think I have to reinstall system,it has experienced 0 free space on root partition)
