A Linux system account: what it is, and which numbers it holds.
What this account is
Purpose unresolved. Debian's own account documentation records no files known to be owned by this user or group, and finds no mention of it in the FHS, in Debian Policy, or in the relevant package changelogs. LSB 1.3 classifies it as legacy and directs new software away from it.
