If the .journal file is marked 'immutable' how is data written to it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



man chattr mentions the following [on RH 7.2]

A  file with the `i' attribute cannot be modified: it cannot be deleted
or renamed, no link can be created to  this file  and  no  data  can  be
written to the file. Only the superuser can set or clear this attribute

The .journal file has the following properties

---i-d------- ../.journal

As such, I am confused as to how data to the journal can be written,
does ext3 internal clear/reset the immutable flag before all writes to
the journal
