The mount points detailed have been created intentionally by engineering.
In basic terms, they are a platform specific enhancement to ensure full
application performance is achieved. This is done by changing the way the
Operating System fully utilizes the potential of the CPU for the platform.
The libc_psr libraries implement platform-specific, optimized versions of
block copy and move routines from libc, such as memcpy(). On UltraSPARC
machines, these routines are coded in assembler, and use block load and
store ASI's, prefetch, and other tricks for better performance.
This is enabled using the HWCAP feature of the linker; see the linker
guide for details
Linker and Libraries Guide .
The alternate routines live in the libc_psr_hwcap1.so.1 library. At boot
time, the libc_psr_hwcap1.so.1 library is loop-back mounted onto the
libc_psr path using a combination of the moe(1) utility, and mount -F lofs,
invoked from the start method of the svc:/system/filesystem/root service
(/lib/svc/method/fs-root). As this is a loopback mount, no disk space is
waisted.
This is the only way that this enhancement can be implemented, and at this
time will not be changed. Disabling this functionality is not possible or
supported.
Got a problem with it? Take it up with SMI.

NAME
install-solaris - install the Solaris operating system
SYNOPSIS
install-solaris
install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation,
install-solaris invokes either a text-based installer or a graphical installer.
The following minimum requirements for physical memory dictate which features are available during installation:
For SPARC machines:
128 MB
Minimum physical memory for all installation types
128 MB
Minimum physical memory required for windowing system
384 MB
Minimum physical memory required for graphical-based installation
For x86 machines:
256 MB
Minimum physical memory for all installation types
256 MB
Minimum physical memory required for windowing system
512 MB
Minimum physical memory required for graphical-based installation
In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea-
tures available.
install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more
details.
install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
