Line 1: mkisofs is aan utility that creates an [[ISO 9660]] image from files on disk. From the man page for mkisofs,'' "mkisofs is effectively a pre-mastering program to generate the iso9660 filesystem - it takes a snapshot of a given directory tree, and generates a binary image which will correspond to an iso9660 filesystem when written to a block device."'' Developers of operating systems will mainly be interested in Line 9: == Mkisofs, its Clone, and its Emulator == The program '''mkisofs''' is part of the [http://cdrecord.~~berlios.de/private/cdrecord.html~~org cdrtools project] by Joerg Schilling. <~~Source~~syntaxhighlight lang=bash> prog="mkisofs" </syntaxhighlight> ~~</Source>~~ Some quarrels with the GNU/Linux community caused a fork of cdrtools, Line 19: is named '''genisoimage'''. You will find it installed as "mkisofs" on many popular GNU/Linux distributions. <~~Source~~syntaxhighlight lang=bash> prog="genisoimage" </syntaxhighlight> ~~</Source>~~ An independent alternative to mkisofs is GNU's [http://www.gnu.org/software/xorriso/ xorriso], which has an emulation mode that understands the options which are used with Line 29: have it either as package "xorriso" or as part of "libisoburn". GRUB2 script grub-mkrescue depends on xorriso-0.5.6 or newer. <~~Source~~syntaxhighlight lang=bash> prog="xorriso -as mkisofs" </syntaxhighlight> ~~</Source>~~ Even the Linux distributions that ship genisoimage considers it [https://wiki.debian.org/genisoimage outdated and bugged]. If you are not using the UDF hybrid feature of genisoimage, you should probably use xorriso on these systems instead. For EFI, xorriso is mandatory. '''Warning''': Defaults of '''xorriso -as mkisofs''' emulation might deviate from those of '''mkisofs'''. E.g. up to xorriso version 1.4.8 not specifying '''-boot-load-size''' assumed a default of four sectors instead of the entire boot file. == Options and input files == Line 138 ⟶ 147: as /tmp/youriso.iso: <~~source~~syntaxhighlight lang="bash"> $prog -U -b boot.img -hide boot.img \ -V "Your Name..." -iso-level 3 -o /tmp/youriso.iso /tmp/deploy </syntaxhighlight> ~~</source>~~ Note that the ISOPATH for option '''-b''' is relative to the Line 150 ⟶ 159: For more examples see [[El-Torito]]. === Under ~~windows~~Windows === Windows version of mkisofs(through cdrtools) can be downloaded from ftp://ftp.berlios.de/pub/cdrecord/alpha/win32.
