[1mNAME
     [0mdrum - paging device

[1mDESCRIPTION
     [0mThis file refers to the paging device in use by the system.
     This may actually be a subdevice of one of the disk drivers,
     but in a system with paging interleaved across multiple disk
     drives it provides an indirect driver for the multiple
     drives.

[1mFILES
     [0m/dev/drum

[1mBUGS
     [0mReads from the drum are not allowed across the interleaving
     boundaries.  Since these only occur every [1m.[0m5Mbytes or so,
     and since the system never allocates blocks across the boun-
     dary, this is usually not a problem.
