Salut,

Un petit "search google" t'aurait donné :
'root' is not allowed to commit files
When committing a permanent change, CVS makes a log entry of who committed the change. If you are committing the change logged in as "root" (not under "su" or other root-priv giving program), CVS cannot determine who is actually making the change. As such, by default, CVS disallows changes to be committed by users logged in as "root". (You can disable this option by passing the --enable-rootcommit option to 'configure' and recompiling CVS. On some systems this means editing the appropriate 'config.h' file before building CVS.)
