I have read a document which tells me the following 4 things are done by the RAM embedded on disk driver controller. But I don't know what's difference between buffer and cache. Thanks!

Happy New Year!
There are currently four UNIX.COM achievement awards up for grabs, as the say. Here they are, in no particular order:

Another major upgrade on the new UserCP today. I have created the "My Badges" page in the new control panel, and it's looking very cool :)

convuser(8) System Manager's Manual convuser(8)NAME
convuser - convert user profile information between BASE and ENHANCED formats
SYNOPSIS
/usr/tcb/bin/convuser -a [-c] [-i] [-n] [-u] [-R] [-U uid] [-M] [-T template] [-[qv]] [users]
/usr/tcb/bin/convuser -b [-T template] [-[qv]] [users]
/usr/tcb/bin/convuser -d [-n] [-M] [-[qv]] [users]
/usr/tcb/bin/convuser -H
FLAGS -a Converts from BASE to ENHANCED authentication format. This option is incompatible with the -b and -d options. If none of -a, -b,
or -d have been supplied, then -a is implied by any of -c, -i, -n, -u, -R, or -U.
-b Converts from ENHANCED to BASE authentication format. This option is incompatible with the -a and -d options. The conversion in
this case is bring any compatible passwords from the extended profile back to the BASE profile.
-c Causes the conversion for -a to create new extended profiles only. If the -c option is given, existing extended profiles will
remain unchanged.
-d Removes any extended profiles which do not still have corresponding BASE profiles.
-i Cause the conversion for -a to invalidate the encrypted password field in the BASE profile if the change to the ENHANCED profile is
successful.
-n Cause the -a and -d conversions to include NIS passwd.byname map entries in the list of BASE profiles for consideration.
-q Cause non-error output to be suppressed.
-u Cause the -a conversion to leave the migrated passwords still usable. The default is to pre-expire them.
-v Cause more verbose reports of progress to be given.
-M Work on NIS master map files rather than the local profiles. This option works on NIS master hosts only.
-R Cause newly-created extended profiles to be written only to the /tcb/files directory tree (v4 only).
-T template
Causes the creation of new extended profiles to use user template as the template for the account default values. Causes the con-
version for -b to consider only accounts with template as the associated account template.
-U uid Causes newly-crated extended profiles with UID values less than uid to be written to the /tcb/files directory tree (v4 only).
-H Cause an extended usage message to be given and no other processing to be performed.
DESCRIPTION
The convuser utility is used to provide migration between BASE and ENHANCED security levels, as well as to provide support for the use of
existing account-creation scripts. The most common uses are to clean up dangling extended profiles (those without corresponding BASE pro-
files) after the removal of the base profiles, and to create new extended profiles to correspond to newly added base profiles.
EXAMPLES
To remove dangling profiles:
# convuser -d
# convuser -Md To finish the addition of new accounts on a system using NIS to supply the extended profile information:
# convuser -iu
# convuser -Miu To finish the addition of new accounts on a system using NIS to supply the extended profile information:
# convuser -iun
