procfs se v fbsd standardne pouziva jen pro truss a ps -e iirc. 99.99% uzivatelu
to naprosto nepotrebuje. naopak, vzhledem k priblizne 6ti miliardam security
bugum zpusobenym procfs se to ve fbsd nepodporuje a podporovat nebude.

navic... z meho lehce zasveceneho pohledu si myslim ze procfs 1) lze (resp.
neposkytuje presne informace) 2) je velmi silne netestovany az by se clovek
nebal pouzit slova "code rott" ;)

ja osobne bych na masine nic takoveho nemel ani kdyby mi za to slibily... no
proste neco fajn :)

navic... i kdyz to clovek potrebuje (jednou za tisic let) tak neni problem nahrat
pseudofs modul a procfs modul.

p.s. zadny smysl nemel procfs tusim v zadnem fbsd. iirc je to sysv vymysl a v bsd
se to nikdy moc neujalo
