iGreetings to respective residents. Excuse me, haven't found a mailing list for newbies... Experiencing difficulties... Could anybody help? Its about partitioning using fdisk -f and bsdlabel. Trying to assemble a sh script for housekeeping purposes installing freebsd onto a given target Even don't know what is the question... The critical lack of experience in subj stops me from gathering information myself. Supposed one wants to generate fdisk config file so he should have these magic numbers describing disk( usb storage, md, ... ) geometry. There's some mess with this geometry because of legacy problems, as i can see, and because my misunderstanding... Sysinstall offers some geometry, then "recalculates" it= , and if you don't let it to, the new system can be born unbootable, disk sizes returned by atacontrol differ from those returned by fdisk, no visibl= e means to determine flash drive parameters( ex me, i don't now how a google request about it should look like), this magick 63 offset for the first slice, mysterious "raw" part don't edit.. Can someone help with this? Needa create one config for layout with say 50m fat and FreeBSD on all remaining and another with FreeBSD using entire disk. And with bsdlabel+config, if i have the size of the slice, everything further is the question of arythmetics and appending a raw partition to the table. The exact partiton sizes need to be somehow calculated depending on fs or can be arbitrary and aproximate? And some waypoint.. errr... How can i get geometry parameters for ata, usb and md-devices?
