(Tunable Kernel Parameters)

NAME

create_fastlinks - conﬁgure the system to use fast symbolic links

VALUES

Minimum

Maximum

Default

Specify integer value.

DESCRIPTION

When

create_fastlinks

is nonzero, it causes the system to create HFS symbolic links in a manner

that reduces the number of disk-block accesses by one for each symbolic link in a path name lookup. This

involves a slight change in the HFS disk format, which makes any disk formatted for fast symbolic links

unusable on Series 700 systems prior to HP-UX Release 9.0 and Series 800 systems prior to HP-UX

Release 10.0 (this conﬁgurable parameter was present on Series 700 Release 9.0 systems, but not on

Series 800 HP-UX 9.0 systems).

To provide backward compatibility, the default setting for

create_fastlinks is zero, which does not

create the newer, faster format. However, all HP-UX 10.0 kernels (and all Series 700 HP-UX 9.0 ker-

nels) understand both disk formats, whether "create_fastlinks" is set to zero or non-zero.

WARNINGS

All HP-UX kernel tunable parameters are release speciﬁc. This parameter may be removed or have its

meaning changed in future releases of HP-UX.
