This is completely safe as long as you answer the last question -in the negative. There are subtleties that the program detects that are -not fully explained in this manual page. -.Sh CONFIGURATION FILE -When the -.Fl f -option is given, a disk's partition table can be written using values -from a -.Ar configfile . -The syntax of this file is very simple.

Note that bootable -.Fx -partitions (the "/" filesystem) must lie completely within the -first 1024 cylinders; if this is not true, booting may fail. -Non-bootable partitions do not have this restriction. -.Pp -Example (all of these are equivalent), for a disk with 1019 cylinders, -39 heads, and 63 sectors: -.Bd -literal -offset indent -g c1019 h39 s63 -g h39 c1019 s63 -g s63 h39 c1019 -.Ed -.It Xo -.Ic p -.Ar partition -.Ar type -.Ar start -.Ar length -.Xc -Set the partition given by -.Ar partition -(1-4) to type -.Ar type , -starting at sector -.Ar start -for -.Ar length -sectors. -.Pp -Only those partitions explicitly mentioned by these lines are modified; -any partition not referenced by a "p" line will not be modified. -However, if an invalid partition table is present, or the -.Fl i -option is specified, all existing partition entries will be cleared -(marked as unused), and these "p" lines will have to be used to -explicitly set partition information. If multiple partitions need to be -set, multiple "p" lines must be specified; one for each partition. -.Pp -These partition lines must occur after any geometry specification lines, -if one is present. -.Pp -The -.Ar type -is 165 for -.Fx -partitions. Specifying a partition type of zero is -the same as clearing the partition and marking it as unused; however, -dummy values (such as "0") must still be specified for -.Ar start -and -.Ar length . -.Pp -Note: the start offset will be rounded upwards to a head boundary if -necessary, and the end offset will be rounded downwards to a cylinder -boundary if necessary. -.Pp -Example: to clear partition 4 and mark it as unused: -.Bd -literal -offset indent -p 4 0 0 0 -.Ed -.Pp -Example: to set partition 1 to a -.Fx -partition, starting at sector 1 -for 2503871 sectors (note: these numbers will be rounded upwards and -downwards to correspond to head and cylinder boundaries): -.Bd -literal -offset indent -p 1 165 1 2503871 -.Ed -.It Xo -.Ic a -.Ar partition -.Xc -Make -.Ar partition -the active partition.
